Roser, Edina, Minn. (505 Tyler Court, Hopkins, Minn.) Filed June 27, 1963, Ser. No. 291,028 15 Claims. ((11. 221-39) The present invention relates to vendors and more particularly to a vendor which can be utilized for vending many different types of articles including newspapers and magazines.

The problem of vending newspapers and magazines has long existed. Large newspaper publishers lose a great deal of money through theft. There are some news vendors on the market but these require adjustment and individual loading of papers which is time consuming and costly. For example, in order for a news vendor to be operative it must be able to vend (substantially without misses) papers ranging in size from a minimum of 4 to 6 sheets to the very large editions.

The newspapers and news magazines do not have good article definition. The individual items tend to adhere together and are not easily separated. This makes most vendors impractical.

Also, news vendors must be extremely sturdy and have very good locks. thereon in order to prevent pilfering of the coin boxes. The unit also must be operated without vending more than one paper for each coin inserted. Mechanical news vendors have a strange fascination for many people in that they feel compelled to try to get more than one paper for their coins.

The news vendor of the present invention in the form disclosed presents a compact easily manufactured structure which will vend papers from a very minimum of thickness to the large editions, substantially without failure.

As disclosed, the unit is a coin operated vendor that has a substantially horizontal storage hopper, as contrasted to the vendors using vertical hoppers, the articles are not fed by gravity in the device of the present invention. The vendor has feed arms with needle-like prongs that pierce the front portions of the paper or article being vended, lift it up out of its storage hopper, position the paper properly and then the paper is removed from the needles. The paper slides down through the discharge chute to the outside of the vendor.

The motion of the needles is such that the weight of the paper determines the amount that the needles seat into the paper and thus a wide variety of thicknesses can be dispensed interchangeably. With light papers the needles do not penetrate a great amount and with heavy papers the needles seat deeper.

The feed mechanism can be adapted to be used with other items such as paper back books by changing the feed. bar so that these items are lifted from beneath rather than using the needle feed. The changing of the feed bar can be done very rapidly.

It is an object of the present invention to present a coin operated vendor that will work many different products.

It is a further object of the present invention to present a news vendor which will vend papers of different thickness without any mechanical changes.

It is a still further object of the present invention to present a vendor utilizing a unique feeding mechanism to maintain a uniform feed pressure on the item being vended regardless of its thickness.

Another object of this invention is to present a tamper proof vendor.

It is a further object of the present invention to present a vendor that does not use a gravity feed storage hopper.

Other and further objects are those inherent in the invention herein illustrated, described, and claimed, and will become apparent as the description proceeds.

To the accomplishment of the foregoing and related ends, this invention then comprises features hereinafter fully described and particularly pointed out in the claims, the following description setting forth in detail certain illustrative embodiments of the invention, these being indicative, however of but a few of the various ways in which the principles of the invention may be employed.

The invention is illustrated by reference to the drawings in which corresponding numerals refer to the same parts, and in which:

FIG. 1 is a front perspective view of a news vendor made according to this present invention;

FIG. 2 is a perspective view of the device of FIG. 1 with the cover in its open position showing newspapers being loaded into the vendor;

FIG. 3 is a vertical sectional view of the device of FIG. 2;

FIG. 4 is a front elevational view of the device of FIG. 3 with parts broken away to illustrate internal mechanism;

FIG. 5 is a fragmentary sectional view of the device of FIG. 3 illustrating the positions of the feed mechanism of the vendor during a vending cycle;

FIG. 6 is a fragmentary enlarged front elevational view of the cover for the vendor taken as on line 6-6 in FIG. 2;

FIG. 7 is a rear elevational view taken as on line 7-7 in FIG. 3;

FIG. 8 is a fragmentary top plan view of a portion of a feed mechanism of the invention taken as on line 88 in FIG. 3;

FIG. 9 is a fragmentary sectional View taken as on line 9-9 of FIG. 4; and

FIG. 10 is a fragmentary sectional View taken as on line 16-10 in FIG. 3.

Referring to the drawings and thenumerals of reference thereon, avendor illustrated generally at it includes an outer cabinet 11 in which the mechanism for the vendor is mounted. The outer cabinet 11 has a cover member 12 hingedly attached thereto with a transverse hinge 13. The cover member has a front panel 14 and a top panel 15. The front panel 14 has a window 16 therethrough so that people can observe the newspapers, illustrated at 17, in the vendor.

While the example shown in the present application will deal primarily with newspapers, it is to be understood that the vending machine can be used with any type of article with particular reference to newspapers, magazines and pamphlets.

As can be seen in FIG. 2, when newspapers are to be placed in the vendor the cover member 12. can-be opened to position as shown in FIG. 2. The top panel 15 forms a shelf on which a stack 28 of newspapers that are to be placed within the vendor may be placed. This allows the person filling the vendor to set the newspaper stack 29 down onto the cover panel when he removes the old newspapers 17 from the vendor.

Paper storage and feed hopper A stack of newspapers 17 within the cabinet is placed in the newspaper hopper and is set down onto a deck 21. The stack 17 is made up of individual papers 22 which are folded at the bottom edges, as at 23. The bottom fold portion 23 is placed on top of the deck 21. The papers should be reasonably well aligned but the vendor will work with some irregularity to the folded edges. The deck is removable from the cabinet. It is held in place with a rear flange 29 that is integral with the deck and formed by bending the deck downwardly as at 29A.

. i i V V p :9 i i y V. The flange 29 fits between brackets 24, 24and the rear wall 4!) of the cabinet.

The brackets 24, 24 are L-shaped having upright legs'24A and horizontal legs 24B which are fastened to the floor of the veendor, as shown. The

upright legs 24Aare'spaced forwardly from the rear wall 40 a su'fiicient distance so that flange '29 slips between the upright legs and the rear wall. 'This can besecn in FIGS. 3 and 5. The deck has frontbirackets 30 that slip over the front support 25. The deck 21 is sloped upwardly from the. rear wall toward the front of the pared to the vertical storage of most other vendors. Thefeeding of the articles to be vended as shown do not depend on gravity feed.

e A pusher 'plate assembly26 includes a plate member 27 slidably mounted'o'n a pair of arms 28, 28. The

edges of the pusher plate are folded over the outside of 'plate assembly'26 is movable to position wherein it will move the last of the newspapers in the-hopper to the front or upper end of the deck. The edges of the plate member 27 areiformed over the arms 28, 28 as shown at 27A and 27B and will slide along the surface of the "deck as the. arms swing. This means that the plate slides longitudinally on the main portion of the arm. The movement of the pusher plate assembly is son The deck is substantially horizontal as .com-

trolled by a pair of springs 34, 34 each of which is at- -tached to one'of the arms '28, '28 as at 35, 35. The springs extend down along the main portion of the arms 28 and over a pair of pulleys'36, 36 rotatably mounted at the lower ends of the arm. The springs then extend forwardly and are attached as at 37, 37to the front support 25 of the deck.

V Attaching the springs in this manner causes them to exert a. large force against the papers when the stack is on the deck is large and a lesser force when the stack decreases. When -the'stack is lighter'the force necessary is less and the spring arrangement compensates for removal of papers.

When the pusher plate assembly is adjacent the front of the deck the springs 34 are substantially straight 'a'nd'ex'er't very little force on the pusher plate. i

As can be 'seen'the arms 28, 28 extend downwardly.

The spring 44 also exerts some forwardlydirected force on the pusher frame. This is particularly true when the frame is far forwardly. The spring 44 insures that the last papers are moved into position to be vended.

advances it is prevented from its locking holeto release the pusher frame.

collar 47 is provided to prevent'the A st p rod from moving too far throguh the deck.

At the forward edge of the deck 21 there are a pluralit V of upright stops 48 attached to the deck. The stops are relatively short and stiff. and form a portion. of the brackets used to hold the deck onto 'the'front supports 25. engage the paper stack 17 and prevent it from sliding forwardly off the deck under the urgingspring 34. A separate leaf spring guide member 49 is positioned on the outside of each stop 48 'and is held fixedonthe stop with rivets or bolts 49A which also hold the stops 48 to the deck (see FIG; 3). The upper "ends of members '49 are bent soas to bear on the papers above the stops. The springs 49fpermit a paper to beslid upwardly. The "springs 49 will immediately engage the next paper in the ,stack. The forward "surfaces of the springs provide a The individual papers 22 are removed from the deck 21 and fed through a discharge chute 50 with a feed mechanism or unit which permits accuratefeeding of papersofall sizes. The discharge chute is comprised as a bottomcurved plate 51 fastened to the cabinet and to the front support 25. The chute has an opening port "52 at the front of the cabinet and a trap door 53 is hingedly attached to the curved plate 51. The trap door -is spring loaded with a small torsion spring 53A so that the free edge normally abuts against a chute front wall 54. The trap door 53 is positioned so that a person can- 'not insert his hand without operating'the feedmechanism.

The trap door easily swings downwadrly out of the way against the curvedpotrion 51 to permit a paper to drop through thechute; V

The feed-unit includes a drive arm assembly 55. W The 'drive arm assembly 55 is comprised as a substantially -U-shaped frame having aback member 56 and a pair of parallel side arms 57, 57 integral with and extending forwardly from the. back member. A pivot shaft 60 is fixed with respect to and extends between the side arms 57, 57 adjacent and substantially parallel to the back member 56. The pivot shaft 60 extends outwardly beyond the side arms and is rotatably mounted at opposite ends thereof in brackets61, 61 which are attached to a floor 62 of the cabinet.

A transverse feed 'bar'assembly 63 includes a feed bar '58 that has endpins -59 pivotally mounted to drive arms 57, 57 at their forward ends and retained between the arms 57, 57 by spring pressure from the arms The feed bar assembly thus can bechanged without any tools by springing the arms 57, 57 apart to clear one of the pins 59. The feed bar assembly has a pair of pick up or feeder arms 64, 64 mountedthereon'. Feeder arms are attached to the topof the feed barwith'hinges 69 (see FIG. 9); Eachv of the arms has a pair of feeder needles 68 mounted at the top end thereof.

Apair of feeder arm stops'65, 65 are fixedly attached -to the feed bar and positioned on opposite sides of the 7 bar from the feeder arms. A separate pick up arm spring The aid in loading the feed hopper, a rod 45 is slidi ably mounted in brackets 46, 46 which are attached to the rear'pusher plate. As shown in FIG. 7 the rod can be insertedthrough a hole provided in the deck 21 and thus hold the pusher frame in a rearwardly position while a stack of papers is loaded into the feed hopper. When the hopper is loaded the rod'can beremoved from 66-is positioned between each of the feeder arms and its associated stop resiliently urges the p feeder arm away from the stop. The feeder arms are mounted so that they will not moveawayfrom thestops 65 past position as shown in FIG.3. The feeder arms will pivot toward the stops 65'and are restrained from this pivoting only by springs '66. The pick up arm springs 66 are a leaf-type spring of relatively low rate. A release bracket 67 is The stops 48 project upwardly above the deck and attached to the bar 58 adjacent a first end thereof. release bracket extends forwardly from the bar.

A control bracket 7% is i'hredly mounted to the feed bar assembly adjacent the first end thereof and aligned with and on the opposite side of the bar from release bracket at. The control bracket 76 has a slot 7} provided therethrough. A control arm 72 is pivotally mounted as at 73 to a first of the side drive arms 57 of the drive arm assembly 55. The control arm 72 has a hired 1y mounted control pin 74 that is slidably mounted within slot 71. An anchor pin '75 is mounted on the opposite end of the control arm 72 and extends outwardly therefrom. A spring 76 is mounted on the anchor pin 75 and also is mounted as at '77 to a side member 78 of the front support of the deck.

The control arm 75 and spring '76 regulate the pivoting of the feed bar assembly about its mounting points. The drive arms move downwardly when a paper is to be vended. This causes the mounting 7'7, pivot 73 and pin 75 to go over center. After the three points have gone over center the force from spring 76 will cause the control arm to pivot about its pivotal axis at 73 and move the feed bar assembly. This will be more fully explained later.

The

Actuator system The actuator system for the vendor includes the operating handle and its associated linkages. The vendor, of course, is coin operated and the coin unit forms part of the actuator system.

A conventional purchased coin operated unit 85 is mounted against one side wall of the cabinet. An infeed chute 85 is positioned so that it is open to a coin slot 87 provided through the front wall of the cabinet. The infeed chute 86 directs the coin from the slot through a coin rejector 88 which will either transfer the coin to a. rejection chute 89 or will divert the coin through the coin operated unit and thus into the money box illustrated at 9i).

It a coin is placed in the slot and the ooin is diverted into the coin operated unit, a shaft 93 in the coin operated unit is free to move through one cycle. An actuator arm is drivably mounted on the shaft 93 as shown in FTGS. 3 and 5.

If the rejector rejects the coin it will be deposited in the paper chute and returned to the customer.

A rod 95 has an end portion that is pivotally mounted through a provided opening at an outer end of arm 94 and the rod extends downwardly through a bracket 96 which is attached to an operating handle 97 that extends through a slot to the outside of the cabinet. The handle 97 is mounted onto a slide bar 133 that is guided by a roller 134 that is rotatably mounted with respect to the cabinet. The rod 95 is held in the brackets 95 with a torsion spring 98. The rod 95 has a notch 95A in the surface thereof into which the actuator portion of the spring seats. This provides a detent action so that the bracket will normally drive the rod 95 but will prevent overloads on the mechanism by slipping if the force on the handle 7 exceeds a certain amount.

When a coin has been passed through the coin unit the handle 97 and associated linkage can be moved downwardly and this in turn will move the rod 95 and the arm 94 downwardly. A drag link 101i is also pivotally mounted to the portion of rod 95 that extends through the outer end of arm 94. The drag link 131 extends downwardly and is mounted onto a pin 102 at an outer end of the adjacent side drive arm 57 of the drive arm assembly 55. The pin 3-92- is mounted through a slot 1 33 at the bottom of the drag link 181. By moving the handle 57 downwardly to the end of its stroke and then again upwardly to its original position, the feed unit will be actuated to dispense a paper out through the chute.

Cover unit locking system The cover 12 is mounted with hinge 13 to the front 6 panel of the cabinet. When the unit isto' be locked the cover is closed and a locking rod 110, which is carried by the cover is passed through a hole in a flange 111 on the cabinet. The locking rod also passes through a flange 112 in the cover member.

The locking rod 110 has a U-shaped end member 113 that is operable from outside the cabinet. Both legs of the U extend into the cover member when the rod is in locked position as shown in FIG. 3. A locking bar 114 is slidably mounted through a bracket 115 at one side of the cover member and is mounted onto a locking arm 116 adjacent the other side of the cover. The locking bar is positioned so that it can be moved to protrude beyond the side edge of the cover member. The locking arm 116 is in turn attached to a tubular eccentric lock member 117 which is operated with a key. The eccentric lock member 117 also controls a second lock bar 118 which may be moved to protrude out the adjacent side edge of the cover. To open the cover, the locking bars are moved to points wherein they do not protrude beyond the side edges of the cover member and with the locking bars in this position the rod 110 is moved to clear flange 111. Then the cover can be opened.

When the unit is to be locked, the cover is closed, the lock rod 119 is inserted through the flanges 112 and 111 of the cover and cabinet and the key is turned to rotate the eccentric lock member 117. This forces the lock bars 114 and 118 to protrude outwardly beyond the side edges of the cover. The ends of the locking bars will thus be inside the cabinet adjacent the front panels that are positioned along the sides of the cover opening. A stop member 12-3) attached to locking bar 114 is against a provided stop collar 11-1 fixed on looking rod lit The member 129 is between the collar and the front of the cabinet so that the rod-110 cannot be withdrawn at sufiicient distance to clear the flange 111. Thus the top panel 15 cannot be pried up nor can the front be pried.

When the unit is to be opened the key is turned the opposite direction and the lock member 117 operates to move the lock bars 114 and 118 so that they no longer protrude beyond the edges of the cover. The cover can then be opened about its hinge 13. By providing a positive lock in two places the cover is substantially jimmy proof and the vendor is not susceptible to loss through theft.

Operation With a stack of newspapers in the vendor, as shown in FTG. 3, a person wishing to have a newspaper will deposit a dime in the slot $7. The coin operated mechanism will then function permitting the arm 94 to be moved. This is done through operating handle 97 which moves the slide Th3 and, through bracket 5% pulls on rod 95. This pulls the arm 94 downwardly activating the drag link 101 and pivoting the drive arm assembly 5'5 about the pivot shaft 6%. The side drive arms 57, 57 move downwardly, as previously stated. As the first side drive arm goes down the pivot '73 of control arm 72, control pin 75 and the attachment point 77 of spring 76 pass over center. The pivot point 73 moves below the spring. The arms 57, 57 are moved further and the force angle of the spring 76 will be great enough to pivot the control pin end of arm '72 upwardly and the other end downwardly. The spring causes a snap action. This in turn will cause pin 74 to move bracket 7 d downwardly and pivot feed bar assembly 63 in direction as indicated by arrow 3.09 in FIG. 5. This occurs after the drive arm assembly has moved substantially to position as shown in FIG. 5. The spring force from spring 76 snaps the control arm over center and in so doing snaps the feeder arms 64 toward the stack of papers. The needles 68, 63 on each of the pick up arms penetrate the front paper in the stack under the action of spring '76 when the unit goes over center. As the feeder arms are hinged on the feed bar 58 the needles are not forced into the front paper except by the inertia from force for. the stack of papers on the deck 21.

' ;spring 76 and the pressure exerted by leaf springs 66.

The slot 71 in control bracket 70 permits the feeder-arms V to move against the stack of papers unrestrained. The

arm s have suflicie'nt freedom so'that they willcontact the front paper even if it is not properly positioned against the Stops48. Also, as the feeder arms'64 are individually hingedto bar 58, they each can move difierent distances The ' gardless of paper size .andposition. Theneedles 68 contact the paper when the handle 97 is at the bottom of its stroke. The handle is then raised which will in turn "raise rod 95 and drag link 102 to raise the drive arm assembly; The needles'68 then tend to pivot toward the paper to be vended as they move upwardly and will become embedded in the front'paper. The amount that the needles embed is determined by the weight of the front paper and its resistance to upward movement. "The paper will be lifted up past the stops 48 and the springs 49. As soon as the bottom folded-edge 23 of the paper being dispensed clears the top of spring-49 the springs will contact the paper immediately behind it under their own force, the stack will be moving forwardly from urging "of the pusher plate assembly 26. This position of the FIG. 5. g

The handle 97 will be moved further upwardly and the release bracket 67 on the feed bar 58, will contact a bracket 124 mounted to the front wall of the cabinet.

The bracket 124 will force the feed bar assembly 63 to pivot so that the upper ends of the pickup arms move extends rearwardly. The stripper bracket 125 will hold the paper from moving forwardly and the action of the bracket 124 on bracket 67 will cause the needles to be pulled out of the paper. The control arm 72 is pivoted "about its pivot 73 to its original position as shown in FIG. 3. The control arm and feed bar assembly are set for another feed cycle.

'paper being vended is shown in dotted lines at 123 in stack sothat the feeder arms can be lifting the front paper easily. v I

Stop members 65 are provided to prevent over deflection of the leaf springs 66. The paper is positively re moved from the needles by the stripper brackets.

The springs 49 over stops 48 insure that a smooth surface is provided for" guiding the paper removed from the stack into the chute 5! Without the spring stops the action of the pusher plate 26 may not be fast enough and a paper could hang up on the front edge of the decl: before the entire stack of papers had moved forwardly.

Again, it should be noted, that asthe stack of papers decreases in size the tongue 42 will engage friction surface 41 and prevent the pusher plate-from moving rearwardly when the pickup arms are tripped so that the needles 68 pi rce the front paper. 7

The feed unit can be used without the needles 6801i articles having good article definition. The arms 64 are provided with fingers or lugs that are positioned below the .deck when the drive arm assembly is in its down position. On the upstroke of the drive arms the lugs engage the bottom edge of the article (corresponding to fold 23) and liftthe article over stops 48 and springs 49. The.

article will be deposited in the chute 5t} in substantially the same manner as the papers.

Where articles with poor article differentiation are vend ed, the needles on the feeder arms give positive results substantially without misses or vending double copies. As many widely apparently different embodiments of this invention maybe made without'departing from the.

spirit and scope thereof, it is to be understood that I do not limit myself to the specific embodiments herein.

What is claimed is:

.. '1. A vendor for paperarticles each comprising a plurality of sheets folded together, said vendor including an outer cabinet, a storage hopper in said cabinet for retaining said paper articles on their folded edge, said hopper including a support deck inclined upwardly in a forward direction, bias means urging said paper articles toward the front of said deck, stop means on said deck to prevent said paper articles from moving forwardly beyond a The paper stripped from'needles 68 will drop down into the chute 50 and the trap door 53 will swing out of the way to allow the paper to 'be removed from the vendor through port 52. i V

Once the handle has again reached its uppermost position the coin operated unit is locked and cannot be reactivated until another coin is dropped through the slot 87. The slot .163 in drag link 1011 insures that the handle 97 must be replacedor pulled up to its uppermost eX- tremity before the paper held. by the needles 63 will be released. This is to prevent jiggling the paper offthe feeder arms before the handle reaches its uppermostposition. The slot 103 insures that the unit will not vend more than one time for each coin deposited.

, In order to shield the coin mechanism from public.

view, a shield 126, which is shown fragmentarily in FIG. 3, can be provided to prevent people looking in from the window17 from seeing the coin operated rnechanisrnf The shield 126 is perhaps best seen in FIG. 2. The shield can be hinged to permit servicemen to swing it out of the way to adjust the mechanism.

The force with which the .papers are pierced by the needle 68 isaccurately controlled through the use of leaf springs 66 as well as the over center snap action under control of spring 76 of the feed bar assembly.
